Material for reinforcing duroplastics woven fabric for reinforcing duroplastics having a specific distribution of hollow thermoplastic microspheres within the thread system

摘要

A reinforcing material for duroplastics made of a web in the form of a woven, non-woven, fiber-woven, or mesh. The web has at least two intersecting and/or interwoven thread systems. One thread system extends mainly across and the other mainly along the web. One thread system partly or completely covers the other. Plastic microspheres with a diameter of 20 to 300 &mgr;m are positioned inside the thread systems. The covering thread system contains approximately 60 to 100% by volume of the microspheres.
